PORATION or MARYLAND Application filed my 2,

This invention relates to accounting ma-' chines in generaland particularly to machines of the type employed for. registering com? mercial transactions in suitable totalizingrdevices, it being broadly an object of the present invention to provide an improved mechanism whereby the'amounts oftransactions may be accumulated and whereby the totals accumulated by the totalizers may readily be obtained.

A primary object of the present invention" is to provide simple and effective means for controlling themovement of any one of a r plurality of totalizers into and out of engagement with certain. actuating elements.

It is a common practice, in connection with V certain types of machines well known in the art, to vary the time during a cycle of operation at which a totalizer will be moved into and out of engagement with the operating racks or other driving elements in accordance with the nature of the operation, i. e., whether adding, totaling or resetting. The present invention has particular reference eration and it is one of the objects of the invention to provide a simple construction for cycle at which varying the times during a I I these movements of the totalizer will take 3 place. Asis common'in machines of this class, the machine on whichthe present in vention has'beenillustrated is so constructed as to require three distinct timings of the movement or" the totalizer, one timingv relation being maintained during adding operations, another during grand totaling operations; that isoperations in which it is, desired to leave the totalizer atzero; and still another timing being required for read or sub-totaling operations or. those in which it is desired to restore the same amount to the totalizer wheels as stood thereon previous to the operation. I

' In machines of this class it is frequently arranged so that the totalizer will be moved into engagement with the actuators after the latter havebeen shifted to some difi'erential positions under the control of amount keys.

by thekeysdepressed will be entered into the totalizer wheels. Duringtotaling operations,

in which it is desired to reset the totalizer wheels, on theother hand, it is usually desirable to engage the wheels with the actuators prior to any movement of the latter and, therefore,comparatively early in the opera-' Movement of the ac tuators' then serves to restore the totalizer tion of the machine.

wheels to zero and these wheels upon reaching their'zero positions in some way serve to stop the differential movements of the actuators. The totalizer wheels are then disengaged from the actuators and the latter maybe restored to their normal positions without pinions. I

When, however, itis desired to efi'ect a sub-totaling operation, orone in which the amount standing on a totalizer is desired to be restored toit after it has been set up on suitable type carriers or the like, the operation is similar to a resetting total operation, except that even on the return stroke of theactu'ators, the totalizer wheels are maintained in engagement therewith. Heretofore it has usually requiredthreei separate cam controls for the purpose of providing the three separate timings of the movements of the totalizer. In accordance with the present invention, the three timing relations are brought about by the use of only two cams or equivalent mechanisms". More specifically, the invention contemplates the use of one cam to control the movements of the totalizer during adding. operations, another cam to control themovements of the totalizer during resetting total operations andthe combined action of thesesame'two cams to control the movements of the totalizer during subtotaling operations. Toward this end, the present invention provides for the production of a relative movement between the pair of cams and a lever or the like operated thereby so as to render one or the other or both of the cams'effective. The camsare so constructed furthermore that they are at all times positive in their action and yet will not interfere with; each other when both are active, as during sub-totaling operations.

any further effect upon the totalizer While the present invention has been shown as applied to a particular roblem in an accounting machine, it will be 0 vious that it is capable of broader application and may be used wherever three camming effects are desired and where these three effects have substantial portions in common.

In the accompanying drawings and the detailed description which follows, the invention is shown as applied to a machine of the type disclosed in the application'of A. A. Dicke, Ser. No. 170,494 filed on February 24, 1927. It will be understood that while this disclosure serves admirably to bring out the simplicity and effectiveness of the invention in the control of a plurality of totalizers it may be used equally as effectively'in many other relations.

With these and incidental objects in view the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

The machine herein disclosed includes various mechanisms common in machines of this class, namely; a driving mechanism, keyboard, differential mechanism, a grand totalizers, and a plurality of transaction totalizers.

The driving mechanism comprises two drive shafts with gear connections whereby these shafts may be caused to make one ro-.

tation by two rotations of a crank handle in either item entering operations or total taking operations.

The keyboard comprises in addition to the usual amount key banks a total control lever and a bank of transaction keys included in which is a grand total key which is utilized in connection with the reading or sub-totaling and resetting of the grand totalizer. The total control lever isnormally in the. Add position during .item entering operations and may be shifted. to a position designated as Read in which the totals standing on the different totalizers may be readily obtained as by causing them to be printed. Shift ng of the control lever to another position designated at Reset will not only cause an operation of the machine :to effect the printing of the totals accumulated by the different totalizers but will incidentally serve to bring about a resetting of the totalizers and thereby condition the machine for a subsequent period of busines.

The general organization and operation of the machine as a whole having been thus outlined, the preferred construction of the various parts above referredto will now be described'in detail.

Operating mechanism To operate the various portions of the ma chine any suitable driving means may be employed, for example, the machine may be equipped with a manually operated crank handle 14 (Fig. 1) whichis loosely mounted upon a stub shaft 15 carried by a frame piece 81 and to which is attached a gear 17 meshing with a larger gear 18 attached to a driving shaft 19. The gear 18 (which is twice as large as .the gear 17) meshes with an idler gear 20 (similaritothe gear 17) the gear 1 2O beingloosely mounted upon a stub shaft 21 projecting-from the frame piece 16. The gear 20 meshes-with a gear 22 (similar to the gear 18) which is securedto a second driving shaft 23. The shafts 19 mg shafts of the machine and they carry cams andotherdevices for operating the va rious parts of the machine as will be described indetail hereinafter as the specification progresses.

lVhile the drawings show the machine as provided with a crank handle for the purpose of manually operating it, it is apparent that themachine may beprovided if desired with anielectricimotor and clutch to connectthe and 23 are the drivmotor with either of the driving shafts 19 and 23.

Amount keg Z2 card and dz'flerential mechanism It is intended that the keyboard in the illustrative machine be provided with groups of settable amount keys for controlling difien ential devices, which, in turn, control the adjustment of type carriers and indicators so that the amount set up may be des gnated in the usual way and may also be entered in suitable totalizing devices. .The mechanism for operating and controlling the differential de-- vices for securing difi'erential extents. of

inove'ment of the totalizing elements, indicators and type carriers as determined by the amount keys forms no part of the present invention and any suitable mechanism may be provided for this purpose.

One form wh ch this mechanism may assume is that shown in the application of A. A.

Dicks, Ser. No. 170,494 hereinbefore men- 7 tioned and the mechanisms whereby the keys control the difierential positioning of the actuating devices will now'be briefly explained. The amount keys. 24 (Fig. 9) are each provided with an inclined edge 25 and a notch 26 adapted to co-operate with laterally xtended lugs 27 integral with a key detent 28. The detent 28 of each bank is supported at its lower and upper ends respectivelyby' arms 29 and 30. Each detent 28. serves in the usual manner to temporarily retain the key in its bank in depressed position, since it will be obvious thatwhen a key is de-' pressed the inclined edge 25 engaging the lug 27 will rock the detent 28 downwardly until the key has been depressed suificiently to bring the lug 27 into co-operationwith the notch 26 and since the d'etent 28 then springs slightly upwardly under the action of a constop pawl 34for the differentialinech anism and since the key will be held in locked position the zero stop pawl 34 will be retained in its disabled position as long as the key is held depressed. Any suitable mechanism may be provided for releasing the depressed keys at the end of the operation of the machine. Since this mechanism forms no part of the present invention it is not described herein and one form. which this mechanism may assume is thatshown in the application to A. A. Dicke, Ser. No. 170,494 hereinbefore men'- tioned. i

The differential mechanism controlled by the amount keys comprises a plurality of sections one of which is provided for each bank of amountkeys 24 and is clearly shown in- Fig. 9. As is shown,there is attached to the driving shaft 23 a box cam 40 the cam slot of which .co operates with a roller carried by the rear arm of abell-crank 41 loosely mounted on a transverse shaft 42; l/Vhile only one cam 40 is shown in the drawings the shaft 23 is adapted to carry, two cams 40 identical with each other, each of which co-operates with its associated bell-crank 41 and between the ends of the bell-cranks there is extended a universalbar or rod 43. The configuration of the cam slot in the cam 40 is such that when the shaft 23 is rotated in the direction of the arrow (Fig. 9) the bell-crank will remain substantially stationary for a partial movement of the shaft 23 and cams 40 after which the cam slot is effective to rock the bell-crank 41 and rod 43 forwardly to a gradually increasing extent and after a maximum movement has been given to the rod 43 the latter will remain substantially stationary.

during another portion of the continued movement of the shaft and cam 40. The movement given to the rod 43 during the reinainder of the movement of the shaft 23 and cam 40 is substantially a counter-part of the first portion of the movement. his will result first. in holding the rod shifted and then givinoit a return slightly beyond its normal position and finally after it has reinained substantially idle. for a While, it will be brought to normal. 1 The return movement of the rod serves to actuate the differential mechanism of the machine which will now be described in detail.

The universal rod 43 is adapted to co-operate with a cam slot 44 formed in a floating lever 45, theforward end of which is adapted to co-operate at the desiredtime with the stem ofthe depressed key, but it is retained in the position shown in Fig. 9 abutting against a projection 46 of the framework by T means of a spring 47. The lever which is in the form of a cam member'is pivoted by means of a pin 48 to an arm 49 whichis se-' cured by means of pins 50 to a complementally movable lever 51 whichhas integral,

therewith a segment plate 52 loosely mounted upon a fixed pivot 53 which in the illustrative embodiment comprises a transverse supporting shaft mounted in the various side and intermediate frames and in the central part of the machine. The forward end of the lever 51 is normally in engagement with the lower edge of a nose projecting from the zero stop pawl 34 while theforward end of the lever 45 is normally in such a position that when the uppermost key, which is the keyof the highest value in the bank is depressed, it is substantially in contact with the rear side of the inner end of this key.

The operation of the differential mechanismis as follows: When a key is depressed the zero stop pawl 34 is rocked forward so crank handle is operated the shaft 23 is rotated and such movement of the shaft will rock the rod 43 about the pivot shaft 42 and this movement of the rod is adapted to move the members and 51 complementally, the

extent of movement imparted to each member being dependent upon the key depressed. The spring 45 will be given a sufiicient tension to hold the lever 45 at normal until the companion lever 51 has been moved. \Vhen the shoulder of the lever 51 engages the inner end of a depressed key further movement of that lever is prevented and movement of the lever 45 continues until its shoulder engages the inner end of the depressed key. For example, if the 8 key has been depressed the inner end of the stem of that key will be moved in the path of the complementally moved members 45 and 51 and as the machine is operated the rod 43 may first cause the lever 51 to pivot around the shaft 53 and move its outer end upwardly until the shoulder engages the stem of the depressed key. During this movement the member 45 tends to pivot about its upper end in contact with the projection 46 so that the pin 48 serves to transmit the motion of rod 43 to arm 49. As the rod 43 continues its movement around its pivotal point 42' it cannot impart a further upward movement to the lever 51 due --to the contact of the latter with the end of the depressed key so that the rod 43 will now by its co-operation with the lower edge of the cam slot 44 cause the lever 45 to be rocked counter-clockwise about its connection 48 with the arm 49 until the shoulder of the lever 45 engages the rear or upper side of the 8 key. The movement which is given to the segment plate 52 and lever 51 will, therefore, be of eight unlts in length while a complementary movement of one unit will be given to the member 45. lVhen a 4 key is depressed the segment plate 52 will be given four steps of movement and the cam lever 45 will be given five steps of movement.

If the machine is operated with no key in the bank depressed the zero stop pawl 34 for that bank remains in operative relationship with the lever 51 so that the latter will not move while the cam lever 45 will be given nine steps of movement. This, of course, will merely result in rocking the cam lever 45 downwardly about its pivotal point 48 during the first half of the operation of the cam 40 and returning it during the second half of the operation with a result that no movement will be given to the segment plate 52. At the end of the first half of the operation when no key has been depressed thev parts will be in the position shown in dotted lines in Fig. 9. By. half operation is meant a half rotation of shaft 23, which brings arm 41 to rest in the dwell portion of cam 40.

Summarizing therefore, it will be noted that the segment plate 52 will be iven a differential movement during the first art of the operation of the machine and it w1ll then return the same a difi'erentialdistance, during the last half of the cycle of operation, these movements being utilized to adjust indicators and printing segments and to operate the totalizing mechanism as will be described hereinafter in detail.

Attention is called to the fact that the formation of the cam slot 44 in the floating lever 45 is such that when the two members 45 and 51 are brought together on opposite sides of the depressed key (or of the nose of the zero stop pawl 34) the curvature of the slot 44 will be concentric with the fixed pivot 53 of the rack plate Furthermore, at this time the concave forward edge 54 (Fig. 9) of the member 45 will always be brought into contact with the hub portion of the segment 52.

The differential mechanisms of the differcnt banks are adapted to adjust a plurality of actuating racks to variable extents commensurate with the value of the keys depressed. Each bank of amount keys adapted to control its corresponding differential rack and each rack in turn is adapted to imparta differential movementto the related tctalizcr element. Each rack plate 52 associated with the amount key differential (Fig. meshes with a segment attached to one oi a series parallel shafts 56 each shaft having rigidly secured to it towards one end somewhat similar gear segment 57 (Fig. and the segments 57 which are secured to be different transmitting shafts 56 are located to one side of the machine and each in a plane in which corresponding denominations of a plurality of totalizers are located as will be explained hereinafter. The var1- ous segments 57 mesh with teeth formed on the lower edge of actuating segments designated by reference character 58. The s ries of se ments 58 related to the various denominational orders are loosely mounted upon the fixed shaft- The racks 58, it will be clear therefore, are adapted to be moved to dilferexr tial extents under control. of the amount keys and on movement in one direction are adapted to be engaged with the totalizcr pinions 61 (Fig. 7) for driving the latter.

Transaction bank of keys Since it is considered advantageous, to segregate the various items entered, in the machine according to some suitable classification the illustrative machine has been provided with a number of totalizers by means of which various totals of the segregated transactions may be obtained. In, the embodi ment shown the special keys which are ini notch 70 adapted to co-operate with laterally;

Each transaction key is also .providedwith an inclined edge 69 and a extending lugs 71 integralwitha key detent 72. The detent is supported at its lower and upper ends resp'ectively by arms 7 3 and 7d and it will serve-toten'iporarily retain the key in depressed position by virtue. of

the co-operation of the lug 71 with notch 70. It will be understoodjthatwhen a key is-depressed the inclined edge 69 engaging the lug 71 will rock thedetent 72 downwardly until the key has been depressed sufficiently to bring the notch opposite the lug 71 and since the detent 7 2 then springs slightly up wardly under the action of a connected spring (not shown) the lug 71will enter the notch 70 of the key and hold the latter depressed against the force of the key return spring The arm 7 3 is provided with a rearward extension 75 engaging a pin 76 carried by a pivoted zero stop pawl 77 forthe transaction.

, Multiple tetaliaers p 7 As has already been mentioned a totalizer appropriated to each of the transaction kevs, designated FRece1ved on account,

,Charge and Paid out, a supplemental totalizer being provided also for accumulat- 111 3, cash sales entered 1n the machine. Cash sales are entered by simply depressing the" amount keys and then subsequently'operatr ing the crank handle, no special key being provided so that during such transactions no transaction key is operated. In addition to the above described totalizers, another total.- izer is provided which is "designated as the Grand totalizer, which is intended inthe embodiment shown to accumulate all the items entered in the Charge and Cash totalizers thus representing the total amount I of salesperformed during some arbitrary period.

Since the construction of thevarious total izers 18 the same a descrlption of one Wlll suffice forall. v Each totalizer comprises a frame 80 (Figs. 1 and7) journaled by means of pins 82 between a pair of totalizer supporting frames 81. Each totalizercarries atotalizer wheel supportingishaft 83, said shaft carry.- ing the plurality of pinions 61 hereinbefore mentioned. During operations of the machine the totalizer frames are adapted to be rocked about the journal pins 82 as a center to bring the totalizer pinions 61 into and out of mesh with the segmental racks 58 by means which will presently be described. As best shown in Figs. 1 and 3, there is attached to each totalizer wheel supporting shaft 83 a downwardly extending arm 84 the lower end of which slides in a slot 85 formed in one of the .totalizer supporting frames 81, and each arm 84 is provided witha groove 86 substantially concentric with respect to shaft 58.

Transaction dz'fierential mechanism The difierential mechanism for the trans action key bank which is adapted in the illustrative machine to select the proper totalizer for operation may also be used to adjust type carriers of a printing mechanism and to differentially adjust an indicator whereby there will be designated in different forms the transaction key operated.

7 Referring particularly to Figs. 1 and?) it will be seen that the difierential mechanism for the transaction key bankis similar in con- I struction to the amount differential mechanism and comprises a pair of complementally moved levers 90 and 91. A pin or roller 92 carried by an arm 93 loosely mounted upon cam slot 95 formed in'the floating lever 90,the forward end of which lever is adapted to cooperate during an operation of the machine with the upper side of the stem of the depressed key, but is normally urged toward the position shown in Fig. 1 by a spring 96. The lever 90 is pivoted by means of a pin 97 toan arm-- 98 which is secured by anysuitable the shaft 42 is adapted to co-operate with a roller 100 engages a slot formed in a box cam 102 mounted for rot'ative movement with'the driving shaft 23. For the purpose of the explanation which follows the cam slot in the cam 102 (Fig. 1) which is effective during item entering operations has been divided into various sections whichhave been designated by'reference characters 103, 104, 105

and 106. H In normal adding operations, as the crank handle is turned, the shaft 23 will be ro tated in the direction of the arrow shown in 4, and during the initial operation of the crank the roller 100 will enter the portion of the cam slot designated 103 which is substantially concentric with respect to the shaft 23. Cam slot 144 will be inefiective during normal item entering operations because it is not cut'as deep as the slot 103 into which the roller 100 extends substantially the full depth on item entering operations. During this initial movement of the operating mechanism the roller 100 and, therefore, the arm 93 will be held in normal position thus permitting the item actuating racks 58 to be moved to their differential positions under control of the amount keys during a time in which the racks 58 and totalizer pinions 61 are disengaged from each other. At substantially the point in the cycle at which the racks have received their full differential positioning the roller 100 will enter that portion of the slot designated by reference character 104 which is eccentric with respect to the shaft 23 so that the cam will be effective to rock the arm 93 clockwise (Fig. 4). As the cam continues its movement it will rock the roller 92 downwardly and toward the front of the machine and as will be described in detail hereinafter it will force the associated levers and 91 to close upon the opposite sides of the depressed transaction key to cause the engagement of the desired totalizer with the positioned actuating racks. Continued rotation of the shaft 23 and therefore the cam 102 will permit the roller to enter that portion of the cam slot designated by the reference character 105 which is substantially cor centric with respect to the shaft 23, but at a greater distance therefrom than the portion 103. During this period in the cycle of movement of the operating mechanism the actuating racks 58 will be restored to their normal positions and since theyare at this time in engagement with the totalizer pinions they will diiferentially adjust the latter to positions commensurate with the value of the keys depressed. After the racks have been fully restored to their normal positions the roller 100 will enter the eccentric portion 106 of the cam slot thereby giving a reverse movement to the arm 93 and separating thelevcrs 90 and 91 with the result-- ing effect of disengaging the selected totalizer from the operating racks. At the final period in the cycle of operation of the machine the roller 100 re-enters the concentric portion of the cam slot designated by reference character 103 and during this period the transferring mechanism becomes effective.

It will be noted in Fig. 3, that the difi'erentially movable lever 90 is provided with a pin 107 and that pivotally mounted by a pin 108 upon the forward portion of the lever 91 is a cam member 109 formed with an overturned lug 110 and a cam slot 111. A coil spring 112 (Figs. 1 and 2) tends to rock the cam member 109 clockwise until stopped by the co-opera tion of its forward edge with a pm 1101 (Fig. 3) carried by the lever 91.

In order to select the cash totalizer for operation it is only necessary to depress the desired amount keys, the final operation being performed by turning of the crank handle.

Fig. 1 shows the normal position of the parts which they assume prior to an operation for entering an item in the cash totalizer. After a partial operation of the machine the arm 93 will be rocked clockwise (Fig. 4) about the shaft 42 and if no key in the transaction bank has been depressed the zero stop pawl 77 will remain in its normal or effective position to prevent any movement of the lever 91 sothat all of the movement of pin 92 will be imparted to the lever 90 which will be rocked downwardly'until the pin 107 enters the cam slot 111 formed in the member 109. In the normal position of the lever 91, as shown in Fig. 1, the cam plate 109 is so positioned that the overturned lug 110 is already in engagement with the slot 86 of the arm 84 related to the lowermost or cash totalizer 113. As the pin 107 enters the slot 111 it will positivelyrock the member 109 counter-clockwise about its pivotal point 82 and through the lug 110 will draw the cash totalizer pinions 61 into mesh with the actuating racks 58 which, by this time, will have been positioned differentially and will be stationary. As the machine is further operated the racks 58 will be restored to their normal positions through a distance commensurate with the amount keys depressed in the related banks and this will result in entering on the cash totalizer the item represented since the portion 105 of the cam slot (Fig. 4) will be effective at this time to retain the pinions in mesh with the actuating racks. When the racks have reached their normal positions the cam portion 106.will be effective to rock the arm 93 reversely and the initial movement in this direction will, by the disengagement of the pin 1.07 from the cam slot 111 result in the positive disengagement of the pinions 61 of the cash totalizer 113 from the actuating racks 58, while continued operation of the machine will serve to restore the lever 90 to normal position.

As previously stated a grand totalizer 114 (Fig. 1) is provided as the uppermost of the group of totalizers and since amounts added in the cash totalizer represent a part of the total sales transacted during a certain period it is desirable to enter the same amount upon the grand totalizer. It is immaterial so far as the present invention is concerned whether the grand totalizer accumulates all amounts of sales or all amounts of cash taken in or any other desired total, but as illustrated it is adapted to receive amounts of all 3 sales both cash and charge. The totalizer wheel supporting shaft 83 of the grand totalizer 114like that of the cash totalizer is provided with a downwardly extending arm 84'which, however, is not slotted at its lower endbut is provided with a pin 115 engaging a closed slot 116 of a plate 117 (Fig. 5) the latterbeing provided with an elongated slot to engage the shaft 53. The segment plate 117 is urged to its normal or upper position by means of a coil spring 118 bearing against the shaft 53 and fitted into a socket formed in a lateral integral extension 119 of the plate 117 (Fig. 5). The segment plate 117 is provided with a plurality of projections 120, 121 and 122, the projection 120 normally engaging a pin 123 carried bythe caniming member 109. p It will be obvious from the description ust given that when the pin107 enters the slot 111 of thecamming member 109 and rocksthe latter counterclockwise to bring the cash totalizer into mesh with the operating racks the co-operation of the pin 123 with the extension 120 will serve to force the plate 117 downwardly against the tension in the spring 118 and through the co-operation of the closed slot 116 with the pin it will force the arm 84 related to the grand totalizer 114 downwardly thus bringing the pinions of the latter into mesh with the actuating racks so that the grand totalizer will simultaneously accumulate the same amounts as are entered in the cash totalizer 113.

It is desirable to provide some means whereby accidental movement I of the to,-

talizers into mesh with the actuating racks by virtue of their weight maybe prevented and whereby they may not be improperly forced into operative relationshipwith the racks. To this ,end suitable effective locking devices are provided. v

As shown in Fig. 2, the pin 108 which is the pivotal point of the camming member 109 extends laterally a suflicient extent to pro ject into supplemental segment plate 124 (Fig. 1) loosely mounted upon the shaft 53 and the periphery of which is concentric with respect to the shaft. It willbe obvious that by means of the connecting pin 108 the seg ment plate 124 will partake of the samemovement as the lever 91. from Fig. 1 that the lower ends of the arms 84 related tot-he Received on account totalizer 125, Charge totalizer 126 and the Paid out totalizer 127 normally rest upon the periphery of the segmental plate 124 thus preventing these totalizers from being rocked about their pivotal. points to carry their pinions into mesh with the actuators. The pinions of the grand totalizer 114 arefnormally only spring held against being rocked into co-operative relationship with the 'racksJGO by the cooperation of the pin 115with the closed slot 116 of the spring-urgedplate' 117.

It will be clear also The cash totalizer 113 is spring held in its normal position under action of the spring 112 as well as the spring 118 due to the cooperation of the pin 123 with the projection 120 of'the segmentalplate 117. It will be" noted, however, that the segment plate 124 is provided with a notch 128 which is normally positioned in the path of the rearend of the arm 84 related to {he Cash totalizer so that here will be no interference when this total- 132', the rearmost notch 132 being norma'llypositioned under the lower end ofthe arm 84 relatedto the grand totalizer thereby permitting the grand totalize'r to be drawn into mesh during a cash operation. 3

When it is desired to enter an amount into the machine which represents a Paid out transaction the desired amount keys are depressed and in addition the Paid out key 65 is also depressed, the machine being further operated by the turning of the crank handle. Vv'hen tl e Paid out key 65 is depressed the zero stop 77 will be disabled in a manner previously described. V-hen the crank handie is operated the cam on the driving shaft 23 will rock the arm 93 forwardly (Fig. 3)

about the pivotal point 42 which will result in first rocking the lever 91 upwardly, due to the retarding action on the lever by the spring 9'6 connected thereto, until the extreme forward end of the lever 91 co-operates with the stemof the Paid out key 65 at which time the pin 123 of the camming member 109 will be out of co-operative relationship with the PI'Oj ection 120 and will be positioned over a cut-away portion of the plate 117 between the projections 122 and 121. When the cammingmember 109 is carried up by the lever 91 the lug 110 will be disengaged from the slot 83 of the arm 84 related to the cash totalizer 113 and will then engage the slot 86 formed in the arm 84 related to the Paid out totalizer 127. Since the segmental plate 124 the from the end of the arm 84'of Cash totalizer and will be positioned in rear of the endof the arm 84 of the Paid out totalizer 127. i As the lever 90 subsequently moves downwardly the pin 107 will'enter the camming slot 111 with the result thatthe arm 84 will be drawn downwardly to rock the totalizer pinions of the Paid out totalizer 127 into mesh'with the segmental rac is 58 which will at this time be stationary. Since the lower end of the arm. 84 of the Paid out totalizer registerswith the'notch 128 there will beno interference between this arm and the plate 124 when the totalizer is drawn into mesh with the actuating racks while the periphery of the plate 12% will now prevent rocking of the Cash totalizer. The pin will be positioned over a cut-away portion of the plate 117 so that while the camming memher 109 is rocked counter-clockwise it will not actuate the segmental plate 117 and the grand totalizer pinions will not be engaged with the actuating racks. It will be understood, off course, that after the Paid out totalizer meshed with the differentially positioned actuating racks, the latter will be restored to normal while the totalizer remains in the engaged position, so that the desired amoun; will be entered in the Paid out totalizer. Subsequently the arm 93 is restored and the levers S and 91 are moved away from each other so that the pin engaging the forward edge of the cam slot 111 will positively withdraw the pinions of the Paid out totalizer from mesh with the actuating racks, the final operation of the machine bringing the parts again to the position shown in Fig. 1.

It w'll also he observed that while the notch 128 registers with the lo er end of the arm 84 related to the Paid out totalizer 113 the periphery of the segmental plate 124 on either side of the notch 128 will co-act with the lower ends of the arms S4: of the Cash totalizer 113, the Charge totalizer 126 and the Received on account totalizer 125 so that their pinions may not intention ally or accidentally be forced into operative relationship with the actuating racks. It should also be observed that counter-clockwise movement of the segmental plate 12 will also adjust the segmental plate 129 attached thereto so that its outer periphery in stead of a notch co-operates with the lower end of the arm 8- of the grand totalizer 114, thereby looking it in its normal position.

When it is desired to enter an amountin the Charge totalizer the Charge key 6 1 is depressed which will result in the engagement of the lug 110 of the camming arm 109 with the slot 80 of the arm 84 of th Charge totalizer 126 so that this latter totalizer will be meshed with the actuating racks and operated ditlerentially in a manner similar to that just described. It should moreover be observed that when the Charge totalizer is selected for operation the pin 123 of the camming plate 109 will be positioned over the lug 122 of the plate 11'? so that the grand totalizer 114; will simultaneously receive the same amount that is entered in the Charge totalizer 126.

Received on account transactions are entered in substantially the same manner, with the exception that the Received on account key 62 will be depressor which will result in the engagement of the pinions of the Bee ceived on account totalizer 125 with the actuating racks 58. Attention is directed to the fact, however, that when amounts are entered in the Received on account totalizer 125 the item will not be entered in the grand totalizer 114, since the pin 123 is positioned over a cut-away portion of the periphery of the plate 117. It will be noted, therefore, that in the illustrated machine only the Charge and Cash transactions will be accumulated in the grand totalizer' thus giving a grand total of all the sales transacted as distinguished from cash taken in or any other item which it might be desired to automatically total.

\Vhile the arrangement shown and described permits the grand totalizer to indicate the total amount of Cash and Charge business transacted, if it is desired to have the grand totalizer indicate the total amount of the cash received it is only necessar to have projections similar to 120 forme on the plate 117 in line with the Received on account and Cash totalizers and to omit such projections in line with the Paid out and Charge totalizers. Vhen the machine is constructed in this manner the grand totalizer will indicate the total amount of cash received and by subtracting the amount standing on the Paid out totalizer from that indicated on the grand totalizer the amount of cash that should be in the cash drawer may readily be determined.

Located in the bank of transaction keys is a key 63 designated as the No sale key for controlling certain functions independent of an entry of a sale. No totalizer is provided for the No sale key and a depression of this key followed by a subsequent operation of the machine merely results in the differential positioning of the levers 90 and 91 so that they may be utilized to differentially adjust the type carriers and indicators to give a suitable designation of the No sale entry. When the No sale key is depressed and the machine operated the levers 90 and 91 will be stopped at a position determined by the stem of the No sale key, the location of the key being such that when the pin 107 engages with the cam slot 111 of the camming member 109 and rocks the latter the lug 110 will not engage the slot 86 of any of the arms 84, and in addition the pin 123 of the camming member will co-operate with a cut-away portion of the plate 117 intermediate a pair of projections. Therefore, no totalizer will not be engaged with the actuating racks when the No sale key is depressed and the difi'erential mechanism is utilized only to impart a movement to a suitable type carrier and an indicator.

T otal taking median 5812i,

The illustrative machine is provided with a total lever 133 which is normally (Figs. 1 and 8) in a position designated as Add in which position the machine is conditioned for accumulating the items entered in one or more of the various totalizers. The controllever 133 maybe moved to two other positions designated respectively as Read and Reset in the first of which the machine is conditioned so that any one of the totalizers may control the differential mechanisms including segments 58 to set upon suitably connected type carriers, such as those designated 600 (Fig. 7 the amount standing on such totalizer and thus permit'the printing of the total upon the record strip. The impression taking means for printing amounts so set up may comprise a platen 603 suitably operated by means such as shown in the application of A. A. Dicke hereinbefore mentioned. Since this means forms no part of the present invention it need not be described further here. Movement of the total lever to the Reset position also permits the adjustment of the type-carriers to print the amounts standing upon the various totalizers, while at the same time the selected totalizers may be reset to zero during successive operations of this character. It'should perhaps be mentioned that in total taking and resetting operations the machine is intended to be operated'by the crank handle 14 just as in the item entering operations.

The shank of the control lever 133 (Fig. 1) is in the form of a rod connected to a bifur cated member 134 which is pivoted by a screw 135 upon the framework of the machine, it being' noted that the upper end of the control lever projects through the machine cabinet (Fig. 8) and is movable in a slot in the cabinet so that a pointer carried by the lever may be placed adjacent the various legends Add, Read and Reset, representing the three types of operation which may be performed. I 0

As is well known in certain classes of ma chines in the art, in taking totals the differential devices and type carriers are adjusted to extents commensurate with the amount on the totalizer by virtue of the engagement of the actuators with the totalizerpinions and the subsequent operation of the actuators as a result of which the pinions are restored to zero.

Referring to Fig. 7 the totalizer elements are rotated in a clockwise direction in adding operations. However, during totaling operations they are reversely rotated so that the totalizer elements may be driven by the racks 58 to extents corresponding to the amounts,

standing upon the totalizer wheels. The movement imparted to each rack 58 is governed at such times by the engagement of the transfer tripping projection 138 (Fig. 7) of the respective order of the totalizer with a trip tooth 139 formed on an arm comprising apart of the transfer mechanism at which time the totalizer element will be at zero and the differential mechanism will be arrested at a point in its movement corresponding to the amount previously on the wheel.

As shown in Fig. 6 the cam 102 has a splined connection to the shaft 23 so that the cam 102 may be shifted laterally without destroying its rotative connection with the shaft 23. T 0 shift the cam 102 laterally to perform different functions, that is, to change the condition of the machine from adding to a totaling condition, as will be described hereinafter, the bifurcated member 134 which is connected to the total lever 133 carriesa pair of pins 136 (Fig. 6)? which are received by an annular groove 13 of a sleeve connected to the cam 102. Since the total lever 133 is pivoted at 135 movement of the upper end of the total lever will, through the connection just described, shift the cam to any desired posi tion. I i I It is essential, of course, in order that the totalizer elements shall control the movement of the actuators and type carriers that the pinions of the selected totalizer shall be meshed with the actuators before the latter.

have beguntheir upward movement (Fig. 7) For this purpose the movement of the control lever to the Read or sub-totaling position, will only shift the cam 102 (Fig. 6) along the shaft 23 to such an extent that the pin or roller 100 is still in engagement with a shallow slot in the cam 102. At the same time a companion cam 140, which is connected to the cam 102 by an annularly grooved sleeve141 and is therefore, also rotatable with the shaft 23 and slidable thereon, is shifted to bring a cam slot therein into co-operation with an opposite extension 101 of the pin 100. It will be understood that in this case movement of the arm 93 (Fig. 3) will be controlled by both of the box cams 102 and 140.

412M totals Adjustment of the control lever to the Read position will permit atotal to be taken from the cash totalizer as will now be explained. As the crank is operated the shaft 23 will be rotated in the direction of the arrows shown in Figs. 3'and 4., the roller 101 describing a path defined by the eccentric portion 142 (Fig. 3) of the cam slot formed in the cam 140. It will be noted that in the beginningof the operation of the machine the arm 93 will be almost immediately rocked clockwise thereby carrying the roller 92 forwardly. Since the arm 91 is held by the zero stop 77 and cannot rise the lever will be rocked downwardly until the pin 107 engages camslot 111 in the cam member 109 and rocks it counter-clockwiseso thatduring the first partial operation of the machine the pinions of the Cash totalizer 113 will be meshed with the actuating racks 58 which are at this time still in their normal positions and stationary. After the pinions are meshed with the actuating racks the roller 101 will travel the initia in a concentric portion 143 forming part of the cam slot in box cam 140. As will be ob served in Fig. 4 the box cam 102 is also provided with an eccentric portion 144 and a concentric portion 145 corresponding to the cam portions 142 and 143 respectively of the cam 140. During the travel of the rollers 100 and 101 in the substantially concentric portions 143 and 145 of the cams 140 and 102 respectively the actuating racks are permitted to be moved upwardly by the regular operation of the differential mechanism and since the totalizer pinions are, at this time, in engagement with the racks, the latter will be turned backwardly until the tripping projection 138 of each totalizer element engages its related trip tooth 139 at which time the rack 58 will be positively stopped just as if it had been controlled by the stem of a depressed key. Since the type carriers 600 are movable with the actuating racks they will be adjusted to positions determined by the totalizer pinions and by any means desired a platen 603 (Fig. 7) may be operated to effect a printing impression upon a record strip of the amount which had previously been standing upon the totalizer. As previously stated, the platen and associated printing mechanism form no part of the present invention and are, therefore, not disclosed in detail in the present application, but reference may be had to the previously mentioned application of A. A. Dicke, for full disclosure of one suitable form of this mechanism.

. Since in sub-total or read operations it is desired to restore the amount subtracted from the totalizer elements the actuators are returned to their normal positions while the pinions are still in mesh with them and for this purpose the arm 93 is held in rocked position by a continuation of the cams 140, and 102. As will be observed in Fig. 4 the roller 100 will pass into a portion 105 of the cam slot in the member 102 which portion is utilized during adding operations as already explained, at substantially the same time the pin or roller 101 will enter a portion 1431 of the groove in member 140.

Attention is called to the fact that the slot 143 also opens up into an eccentric cam slot 146 which as will be explained is effective only in resetting operations. By a comparison of Figs. 3 and 4 it will be noted that the break between the concentric portions 143 and 1431 of cam 140 required for the opening into channel 146 falls at a slightly different point from the similar break between the portions 145 and 105 of cam 102 occasionedby the channel 104 so that one or the other of the rollers 100 and 101 will at all. times be riding in an unbroken race-way during Read or subtotal operations. Thus the portion 145 still exerts its positive action as the pin 101 passes overthe gap leading into channel 146 while part. of section 1431 takes effect to positively hold the arm93 rocked as the pin 100 passes the opening leading from the channel 104.

After the racks 58 are returned to their normal positions an eccentric portion 147 (which is a continuation of the portion 1431) will be effective to rock the arm 93 so that the roller 92 will separate the transaction differential levers 90 and 91 thus ositively withdrawing the totalizer pinions f the actuating racks.

In order to prevent the e agement of the grand totalizer during toilfiing operations such as take place "in adding operations whenever the cash totalizer is carried into mesh, the following mechanism is provided. As will be observed in Fig. 8, the upper portion of the control lever 133 is provided with an integral transversely extending camming portion 148 adapted to co-operate with an arm 149 (Fig. 7) secured to a shaft 150. Mounted upon the shaft 150 and also secured thereto is a bail comprising a pair of forwardly extending arms 151 and a cross rod 152, the latter being in engagement with a slot or notch in a rearwardly'extending arm 153 secured to the shaft 154. This shaft, which as shown in Fig. 1 forms the supporting pivot for the loosely mounted arm 74, has secured thereto a downwardly extending arm 155 (Figs. 5 and 7) which has a pin and slot connection to an upward extension of the plate 117. lVhen the total lever is moved to the Read position it will rock the shaft 150 counter-clockwise (Fig. 7) thereb lowering the cross rod 152 of the bail an rocking the shaft 154 clockwise. By means of the connection 155 from the shaft to the plate 117 the latter will be so positioned that the projection 120 will be disengaged from the pin 123 and will be positioned at a cut-away portion 157 (Fig. 7) between the projections 121 and 120. Therefore, when the Casl1totalizer is rocked into and out of engagement with the actuating racks during totaling operations rocking of the member 109 will not cause movement of the plate 117, and will not cause the engagement of the grand totalizer 114 with the actuating racks.

In order to obtain the total standing on the grand totalizer it is only necessary in the illustrative machine to shift the total control lever to the Read position and then depress the grand total key 66. When this latter key is depressed its action on the detent 72 and arm 73 will be such as to rock the zero stop member 77 to unlock the lever 91. When the machine is then operated the arm 93 will be rocked clockwise under the control of both cams 140 and 102 just as previously described in connection with the Cash totalizer so that the levers 90, 91 will be brought together, the lever 91 first moving upwardly until it strikes the stem of the grand total key and the lever 90 then moving downwardly until it strikes rom mesh with the grand total key. This movement of the arm 91 will just be sufficient to permit the pin 123 to co-operate with the projection 121 of the then shifted plate 117, while it will also carry the member 109 far enough to disengage the lug 110 from the slot 86 of the arm 84 related to the Cash totalizer. Therefore, when the pin 107 engages the cam slot 111it will force the plate 117 downwardly and by means of the closed slot 116 engaging the pin 115 will draw the arm 84 related to the grand totalizer downwardly and immediately engage the grand totalizerpinions with the 15 actuating racks 58. The rest of the-totaling operation for the grand totalizer is similar to that described in connection with the Cash totalizer andwill, therefore, not be repeated.

Printing of the totals standing upon the Paid out, Charge and Received'on account totalizers, after the lever 133 has been shifted to the Read position, is effected by merely depressing the related key and then operating the crank handle so that inv each instance the lever '91 will be moved differentially until the lug 110 engages the slot 86 of the corresponding arm 84 thereby effecting the engagement of the pinions of the desired totalizer with the actuating racks which are then reciprocated to adjust the type carriers differentially and to subsequently Toenter the same amount as was subtracted from the totalizer elements. In obtaining the to tals from the Paid out, Charge and Re ceived on account totalizers, it will be noted that in each case the pin 123 will be located over a cut-away portion of the plate 117 so that the grand totalizer will not be simultaneously meshed with any of the totalizers during total operations. v

Total taking -resettz'ng of totalizers The operations -whereby the totals are printed from the, different totalizers and the totalizer elements are permitted to remain at zero somewhat similar to those previously described for the taking of Read totals, but to accomplish this the total lever must be moved to the extreme rightposition or that designated as the Reset position. This will govcm the action of the totalizer engaging mechanism so that the selected totalizer will be engaged with the actuators only during the 1 movement of the latterin one direction and the wheelswill be disengaged from the actu ating racks when the racks are in their raised or differentially shifted positions thus leaving the selected totalizer wheels at their zero positions.

When the control lever is moved to the Reset position the pair of cams 102 and 140 will be shifted so far that the roller will be entirely disengaged from the slot formed in the cam 102, and the roller 101 will be moved all the way into the cam 140, that is to say deeper into the slot 142 of the cam 140 than was the case for Readtotals so that in resetting operations the 'totalizer pinions will be placed under the control of portions 142, 143 and 146 of this cam. Thus the pinions will be immediately drawn into engagement with the actuators prior to movement of the latter. The actuators will then be moved upwardly to diflerential extents as controlled by the totalizer pinions and after they have come to rest the roller 101 will be at the junction of the slots 146 and 1431 (Fig. I

3). The slotl46, however, is deeper than the slot 1431 so that the roller 101 striking the wall 156 will not be able to pass into the slot 1431 but will necessarily pass into the slot 146 which, as noted, is eccentric to the shaft 23 so that the arms 90 and 91 of the transaction bank will be separated and the zeroized totalizer elements will be withdrawn from the actuating racks. With the exception of the difference in timing just mentioned the resetting operations whereby the 'totalizer elements of the selected totalizers may control the type carriers so that amounts may be printed upon the record strip and the totalizer elements may incidentally be left at zero are similar to those described in connectionv with the printing of Read totals. Vhen the control lever isshifted to the Reset position the machine is normally con ditioned for resetting the Cash totalizer 114.

while resetting of any of the other totalizers may be determined by the additional depression of the related key. r i

Itshould be mentioned that the cam groove in member 102 which is effective duringadding operations, namely channel 103, 104, 105 and 106 is cut deeper than the channel 144, 145 which is effective only during Read total operations. Therefore, when the lever 133' is in the Add position and the cam is so located that roller 100 enters to substantially the full depth of groove 103 the latter will positively control the movement of the arm 93 and there will be no danger of the shallower groover 144 taking effect. Thus there is provided a positive control over'the totalizer engaging mechanism for three different types of'operation, namely, adding, Read totaling, and resetting, by the use of ,only two cams.
